Great, thanks for this hint.
So the solution here is to set, in Karaf's "etc/custom.properties"
org.apache.felix.http.require.config=true
It's not documented at
https://github.com/apache/felix-dev/tree/master/http one has to look at
the source.

Hello
The thread names in your log output explain the "problem".
First the feature service starts Jetty server, but later,
Configuration Admin updates `org.apache.felix.http` PID and CM's
ManagedService from Felix restarts the server based on non-default
configuration.
Usually this "problem" (actually it's an OSGi dynamism in action) is
avoided with options like "waitForConfigurationAdmin", where the
Activator does not start its service if the configuration does not
come from ConfigurationAdmin. We do it in Pax URL Aether and Pax Web too.
I'm not sure if such option is configuration in Felix HTTP.
kind regards

Hi
when loading Felix Jetty12, i.e. using bundles
<bundle>mvn:org.apache.felix/org.apache.felix.http.servlet-api/6.1.0</bundle>
<bundle>mvn:org.apache.felix/org.apache.felix.http.jetty12/1.1.10</bundle>
I'm seeing a weird startup behaviour.
First Jetty comes up on its default port, then immediately it
stops and restarts on the configured port.

Anyone understands why this occurs, and how it can be avoided?
